The purpose of this plan is to reduce the damages in intercity train crash cases to the passengers. In the next phase, if the train catches fire with the increase in the incident time of smoke and fire entering to the train, the passenger is required to react appropriately. The coupe and the corridor are designed to prevent the fuel, fire, heat and wear from penetrating into the coupe so passengers can have plenty of time to get out of the train. In addition to sound proof its walls are heat and fire proof.
